If you could answer the following questions that can be found in the picture that would be great! Thanks.

2. The economy of Champan starts out with inverse AD and SRAS curves given as such: ADITE=140-4Y SRAS: rt=rte+2(YY) Notice that this SRAS curve is expectations-augmented. The level of ination is determined in part by rm exPectations of ination, and how far output deviates from its long run level. We know that V = 32. In addition, we know that the natural rate of unemployment is UN =5. Okun's Law in this economy is (Y T) = -2*(U - UN) a. What is this economy's LRAS curve? b. Suppose that Champan starts in long run equilibrium. What is the expected level of ination? c. Given that we now know SRAS, Y, UN, and Okun's Law, state the Short Run Philips Curve of this economy. d. Champan starts in its initial long run equilibrium as above. Then there is an AD shock that shifts inverse AD to be It 148- 4Y. The government decides not to respond to the AD shock. i. What does it mean to say that individuals have rational expectations? ii. If individuals have rational expectations, how will a... change when the AD curve shifts? iii. What will the SRPC become, under rational expectations, following the AD shift? Draw a graph representing the LRPC and the SRPC shifts that occurred in this
